Does Glamorous Toolkit work for you? It's pharo with a different rust based GUI stack, and some batteries included for making custom inspector views and such. I don't have a high DPI display so I'm not completely confident, but my understanding is that their rust based GUI works fine with high DPI.

I see some movement on high-DPI in the latest release. What are the current gaps? I'm not familiar with the project, just curious.

> Improves high-DPI support for buttons, scroll panes, sliders, menus, multi-selection lists, trees, drop-shadows, the scratch pad, the keyboard exerciser, and others.

Wow, never heard of it! Thank you!

I have at least eight different GUIs implemented in Squeak and also native Xwindows, macOS, iPhone and Windows. Plus several through the FFI interface. And three/seven Web GUI interfaces. We used to run (around 2009) Squeak on more platforms than Linux, they all still work in the 32 versions. I'll make the old bitrotted GUI's work again in the latest Squeak 6.1 if you pay me a few thousand euro's.

I count many more native GUI support in all Smalltalk versions https://github.com/jeceljr/SmalltalkSurvey

Squeak goes back all the way to 1972, we ran on most GUIs in existence. Smalltalk was the invention of the first GUI. https://smalltalkzoo.computerhistory.org

I even have the most scalable (massively parallel) GUI written in a few thosand lines of code: https://youtu.be/f1605Zmwek8?t=3100

And several 3D GUIs https://www.youtube.com/watch?v=1s9ldlqhVkM&t=4s and the highly scalable https://www.youtube.com/watch?v=uQTeWJNkylI

It should not be a problem, given how many love to use CLI and TUI workflows stuck in the 1960-80's. :)
